Why Use 6.38 mm Laminated Glass for Magic Folding Windows Instead of Normal 5 mm or 6 mm Glass?

Visual comparison of annealed glass, tempered glass, and laminated glass breakage patterns — highlighting the safety benefits of laminated glass for folding and bifold windows.

When choosing the right glass for your folding window or bifold windows, safety, noise control, and durability matter. That’s why our Magic Folding Windows are built with 6.38 mm laminated glass — a premium choice that offers significantly better performance than regular glass.

1) Laminated Safety Structure
The 6.38 mm laminated glass consists of two layers of glass bonded with a polyvinyl butyral (PVB) interlayer. This construction holds the glass together even when broken, reducing the risk of injury from flying shards — an essential feature for HDB windows and high-rise properties.

2) Stronger Breakage Resistance
Unlike standard 5 mm or 6 mm glass, laminated glass is harder to break, providing enhanced security against accidental impacts and potential intrusions. This added strength makes it a superior option for modern bifold window systems.

3) Superior Noise Reduction
The PVB interlayer dampens sound vibrations, significantly reducing outdoor noise. If you’re looking for noise-reducing windows for your home, laminated glass is a must — especially for units facing roads or urban environments.

By using laminated glass in every Magic Folding Window, we ensure you get a product that’s not only stylish and functional but also safe, quiet, and HDB-compliant.

Unobstructed View

Both the Folding Window and the Slide and Swing Window are excellent choices for homeowners who want a fully openable window system that offers an unobstructed view and enhanced ventilation. However, they each have unique characteristics that may make one more suitable depending on your space and preferences.

Folding Window

The Folding Window features a thicker and more robust frame. It folds two panels at a time, making it quicker to close — especially useful during sudden weather changes like rain. However, when fully opened, the folded window panels take up more space, which may be a consideration for narrower window.

Slide and Swing Window

In contrast, the Slide and Swing Window has a sleeker, more modern frame that blends seamlessly with traditional casement or sliding windows, making it ideal for homeowners who want a more uniform look across their home. While it operates one panel at a time, offering more control, it may take slightly longer to close compared to the folding system.

If you’re still unsure, consider combining both in your home — install the Magic Folding Window in your living or dining areas for wide, fast openings, and use the Slide and Swing Window in rooms where a compact, minimalist design is preferred.

Folding Window
Frequently Asked Questions

The Folding Window is an innovative window system that allows you to fold all panels to the left, right, or split them between both sides, offering a fully open, unobstructed view and excellent ventilation.

Commonly known as a bifold window or bifolding window, this system typically operates as a pair -two panels folding in each direction, providing flexible operation and a sleek, modern appearance.

Maintaining your folding window is simple and helps ensure smooth, long-lasting performance. Follow these easy care tips:

Clean the glass regularly using a mild glass cleaner or soapy water. Avoid abrasive cloths or harsh chemicals that may scratch the laminated surface.
Wipe down the window frames with a damp cloth and mild detergent. While powder-coated frames are low-maintenance, occasional cleaning helps prevent dust and grime buildup.
Lubricate the hinges and roller mechanism every 6 months using WD-40 or a similar lubricant to keep the folding motion smooth and quiet.
Check the rubber seals for dust, dirt, or debris. Wipe them clean with a damp cloth to maintain optimal noise insulation and airtight performance.

With regular upkeep, your Folding Window will continue to deliver unobstructed views, ventilation, and quiet comfort for years to come.
